1. Field of the Invention
This invention relates in general to latching mechanisms and more particularly to latching mechanisms for use in devices that generate audio.
2. Description of the Related Art
Many electronic devices include one or more latches for coupling together several mechanical components. Latches also facilitate disassembly of the coupled components permitting replacement and/or access to other components contained within. For example, latches can be used to secure a front housing of a device to a back housing of the device. Using latches is desirable because it eliminates the need for screws and screw bosses, thereby lowering manufacturing costs and providing for an increased useable circuit board area. Incorporating latches into an electronic device, however, does require reservation of some space in the device to enable their operation.
Most electronic devices also include one or more speakers for broadcasting audio. With the drive towards reducing the size of electronic devices, particularly portable or mobile units, advances have been made to reduce the size of speakers. Nevertheless, speakers and the structure required to support them take up valuable space in these devices. Additionally, speakers and their supporting structure are constructed and assembled independently of all other components of electronic devices.
The features of the present invention, which are believed to be novel, are set forth with particularity in the appended claims. The invention, together with further objects and advantages thereof, may best be understood by reference to the following description, taken in conjunction with the accompanying drawings, in the several figures of which like reference numerals identify like elements, and in which:

The latch element 120 can include a top surface 132 (see
In another arrangement, the receiving element 131 can include one or more of the audio ports 122 and one or more cavities 148 (see
The removable housing portion 114 can also include any number of tabs 153, each of which can be positioned along the edges of the removable housing portion 114. These tabs 153 can be designed to snap engage one or more corresponding slots 155 located on the front housing 112 (see
The audio plate 128 can include one or more audio plate audio ports 158, an audio plate recess 160 having an audio plate opening 161 for receiving the protrusion 136 of the latch element 120 and an audio plate back port 162. The audio plate audio ports 158 can facilitate the channeling of audio to or from the cavities 148 of the receiving element 131. Further, the audio plate back port 162 can facilitate the channeling of back volume to the back port cavity 150. Similar to the opening 143 of the recess 140, the audio plate opening 161 can include an arc 164 and one or more segments 166 for respectively receiving the shaft 137 and the wings 138 of the protrusion 136. As a result, the audio plate opening 161 can have a shape that is also at least substantially similar to at least a portion of the protrusion 136. In one example, the latch element 120 and the removable housing portion 114 can be constructed of plastic, and the audio plate 128 can be constructed of metal, although those of ordinary skill in the art will appreciate that other suitable materials may be used to produce these components.
In one arrangement, the orientation of the audio plate opening 161 can be approximately ninety degrees different from the orientation of the opening 143 of the removable housing portion 114. For example, the orientation of the audio plate opening 161 can be at least substantially horizontal. It will be appreciated by those of ordinary skill in the art that other suitable orientations are within contemplation of the inventive arrangements.
The front housing 112, which can be constructed of any suitable material, such as plastic, can include one or more front housing audio ports 168 and a front housing recess 170. As best shown in
The front housing recess 170 can further include one or more stops 175 and a blocking surface 177 (see
As illustrated in
The seal 130 can also include a seal plate 180 (see
The seal 130 can house the audio element 126. The audio element 126 can be any component capable of generating an audio output or receiving an audio input. For example, the audio element 126 can be a speaker or a microphone. The audio element 126 can also include one or more contacts 184, which can be used to provide a contact surface for a circuit board or some other device used to convey signals to the audio element 126.
During the initial assembly of the electronic device 100, the latch element 120 can be rotatably coupled to the recess 140 of the removable housing portion 114. Specifically, the protrusion 136 can be inserted through the opening 143 such that the wings 138 of the protrusion 136 are oriented in substantially the same direction as the segments 144 of the opening 143. Once inserted, the latch element 120 can be rotated such that the wings 138 of the protrusion 136 are oriented in a direction that is different from the orientation of the segments 144. For example, the latch element 120 can be rotated approximately ninety degrees in either a clockwise (CW) or a counter-clockwise (CCW) direction.
Following the rotation, the wings 138 of the protrusion 136 can now be at least substantially aligned with the segments 166 of the audio plate opening 161. The audio plate 128 can then be secured to the removable housing portion 114 with an adhesive, although any other process or structure can be employed to do so. Once the audio plate 128 is secured to the removable housing portion 114, the latch element 120, because the opening 143 and the audio plate opening 161 have different orientations, can remain coupled to the recess 140 and can be rotated in a CW or CCW direction.
Continuing with the initial assembly, the projections 172 of the front housing 112 can be inserted through the apertures 174 of the seal 130, and the seal 130 can be positioned against the front housing 112. The seal audio ports 176 and the seal back port 178 can extend beyond the front housing audio ports 168. In view of this feature, the seal audio ports 176 and the seal back port 178 may contact the audio plate 128 when the electronic device 100 is fully assembled, a process that will be further explained below. The seal 130, which can house the audio element 126, can be secured to the front housing 112 with an adhesive; however, one of ordinary skill in the art will appreciate that any other suitable process or structure can be used to secure these two components.
At step 510, the method can begin, and at step 512, a latch element can be mechanically coupled to a housing. For example, the latch element 120 can be coupled to the housing 110 of the electronic device 100. A series of steps may be involved in this process, and each of them will be discussed herein. The latch element 120 can be rotated to a first orientation in which the protrusion 136 is aligned with the audio plate opening 161 and misaligned with the opening 143 of the recess 140. That is, the wings 138 of the protrusion 136 can be aligned with the segments 166 of the audio plate 128 and misaligned with the segments 144 of the opening 143. The protrusion 136 can also be aligned with the front housing opening 169, i.e., the wings 138 can be aligned with the segments 173 of the front housing opening 169. The removable housing portion 114 can then be engaged with the front housing 112 (by engaging the tabs 153 with the slots 155), and the protrusion 136 can be inserted through the front housing opening 169. During this process of engaging the latch element 120 with the housing 110, the keypad 116 (see
Referring back to the method 500 of
As the latch element 120 is rotated to the second orientation, the wings 138 of the protrusion 136 can engage the blocking surfaces 177 (see
At this point, at least a portion of the housing 110 can be mechanically coupled between the latch element 120 and at least a portion of the secondary latch element 124. For example, the front housing 112 can be coupled between the latch element 120 and the seal 130. At least a portion of the secondary latch element 124 can also be mechanically coupled between the audio element 126 and at least a portion of the housing 110. For example, the seal 130 of the secondary latch element 124 can be coupled between the audio element 126 and the front housing 112. The audio plate 128 can be mechanically coupled between the latch element 120 and at least a portion of the housing 110, such as the front housing 112.
When the electronic device 100 is assembled, including when the latch element 120 is engaged within the housing 110, several audio passages can be formed. In particular, the seal audio ports 176 and the seal back port 178 can be at least substantially aligned with the audio plate audio ports 158 and the audio plate back port 162. Because they can extend beyond the front housing audio ports 168, the seal audio ports 176 and the seal back port 178 can be at least partially in contact with the audio plate 128. Thus, the seal audio ports 176 and the audio plate audio ports 158 can form a secondary latch element audio port 186, as best shown in
